Little details are important. A little thing out of whack can get the attention of someone of someone who knows how things are supposed to be.
I used to work for the Queensland Police, and I really impressed them once by identifying a counterfeit twenty dollar note from across the room, while it was in a bag. I couldn’t tell that the note was printed on paper instead of plastic, or that the holograms were missing… but I could see that it wasn’t exactly the right shade of red. (Australian twenties are orange-red) I’d worked for years in a supermarket, and one of the few things I do remember well is colour. I see a scarlet red instead of an orange red on a twenty and I know something is wrong.
Someone who handles money all day – and pays attention to it – is much more likely to spot a forgery than someone who only uses it to buy things. Someone who spends all day taking care of kids will notice the signs of illness, especially in a kid they know, before a non-expert. Someone who spends all their time in a particular place – the woods, the city, whatever – is going to notice something out of place that no visitor would.
… I had to get up and deal with the kid and now I have no idea where I was going with this.
So, I really like coffee. But I don’t like good coffee. I like cheap instant with way too much sugar. I’m really bad at liking coffee, or so I’m told by *real* coffee-lovers. But I don’t care. I like it how I like it and it works for me.
Coffee fandom is a lot like most other fandoms, when you get right down to it. Everyone thinks their flavour preference is the best, people get really passionate about what sweetener their coffee is shipped with, and they can be very judgemental of other fans who don’t like coffee properly. Seriously, walk into a Starbucks and order a plain black coffee, or ask for a mocha frappucino in a nice cafe, and see how people look at you. It’s Avengers Movieverse vs 616 all over again.
So it can be a good way of explaining fandom. A lot of people drink coffee, and they understand that drip vs instant is a whole big thing, and sometimes if you can find a comparison they understand, people can transition from ‘god, you’re so weird for being so obsessed with fictional characters’ to ‘God, you are not seriously comparing Captain America to a cappucino how does coloured ink on paper compare to SWEET CAFFIENE’.
Well, it’s not perfect. But if you’re trying to explain fandom to a Muggle, coffee isn’t a bad gateway obsession.
